connected component labeling problem in a graylevel image without background [message #32507]

Hi, there,

I have a problem here:
" The problem is like a grayscale photograph of a jar of
marbles. Each marble is uniformly gray. All the marbles are touching each
other, so there is no
background. Two marbles of the same color may not belong to the same
region.
I want to give a unique label to each marble/region."

Now I am solving this problem in this way:
First, use WHERE or HISTOGRAM to get a mask of regions
at each gray level, and then use LABEL_REGION on each mask.

However, this method is not efficient since it needs to scan the image
for several times.

Can I do it only in a raster scan of the image?

Any suggestion will be appreciated,

Julia
